Q. What is the value of A when we rewrite 15x as A6x ?Choose 1 answer:(A) A=15−6(B) A=156(C) A=15−61(D) A=615
Expressing 15x in A(6x) form: We need to express 15x in the form of A(6x). To do this, we need to find a base A such that when raised to the power of (6x), it is equivalent to 15x.
Equating the exponents: Let's assume 15x=A(6x). To find A, we need to equate the exponents of both sides. Since the exponent on the right side is (6x), we need to find the sixth root of 15 to make the bases equal.
Finding the base A: Taking the sixth root of 15 is the same as raising 15 to the power of 1/6. Therefore, A should be equal to 151/6.
Comparing the options: Now we compare the options given to find which one matches our result:(A) A=15−6 is incorrect because it represents the reciprocal of the sixth power of 15, not the sixth root.(B) A=156 is incorrect because it represents the sixth power of 15, not the sixth root.(C) A=15−(61) is incorrect because it represents the reciprocal of the sixth root of 15.(D) A=1561 is correct because it represents the sixth root of 15, which is what we need for A.
