Q. If 2×5=9 and 4×0=16 and 8×3=67, and 3×8=17, what is the value of 8×8?(A) 64(B) 65(C) 66(D) 72(E) 68
Analyze Pattern in Rules: We need to understand the pattern in the given operation rules. Let's analyze the first rule:25=9This does not follow the standard exponentiation rules, so there must be a different operation being applied here. We need to find a pattern that applies to all the given rules.
Examine Rule 1: Let's look at the second rule:40=16Again, this does not follow the standard rules of exponentiation, as 4 to the power of 0 should be 1. We need to continue looking for a pattern.
Examine Rule 2: Now, let's examine the third rule:83=67Standard exponentiation would give us 512, not 67. We need to find the relationship between the base, the exponent, and the result.
Examine Rule 3: Let's analyze the fourth rule:38=17This also does not follow the standard rules of exponentiation, as 3 to the power of 8 should be 6561. We need to find the pattern that connects the base and exponent to the result.
Examine Rule 4: By examining the given rules, we can see that the operation defined by "**" does not correspond to exponentiation. Instead, it seems that the operation takes the base and adds it to the exponent to get the result. Let's test this hypothesis:For 2∗∗5, the base is 2 and the exponent is 5. Adding them gives us 2+5=7, but the result given is 9, which is 2 more than 7.For 4∗∗0, the base is 4 and the exponent is 0. Adding them gives us 20, but the result given is 21, which is 22 more than 4.For 24, the base is 25 and the exponent is 26. Adding them gives us 27, but the result given is 28, which is 29 more than 50.For 51, the base is 26 and the exponent is 25. Adding them gives us 54, but the result given is 55, which is 56 more than 50.It seems that the pattern is not simply adding the base and the exponent. We need to find a consistent operation that applies to all given rules.
Test Hypothesis 1: Upon closer inspection, we can see that the result is always one more than the product of the base and the exponent. Let's test this hypothesis:For 25, the base is 2 and the exponent is 5. Multiplying them gives us 2×5=10, and adding 1 gives us 11, but the result given is 9. This does not match our hypothesis.
