Q. Select all the expressions that are equivalent to 36×96.Multi-select Choices:(A) 27−61(B) 2712(C) 2761(D) 2736
Recognize 9 as Power of 3: We need to simplify the expression 36×96 to find equivalent expressions.First, we recognize that 9 is a power of 3, specifically 9=32.So, we can rewrite 96 as (32)6.
Apply Power of a Power Rule: Now we apply the power of a power rule, which states that (ab)c=a(b∗c). So, (32)6 becomes 3(2∗6) or 312.
Multiply Exponents of Same Base: Next, we multiply the exponents of the same base in the original expression.So, 36×312 becomes 36+12 or 318.
Compare to Choices: Now we have simplified the original expression to 318. We will compare this to each of the choices to see which are equivalent.
Simplify Choice (A): For choice (A) 27−61, we recognize that 27 is 33. So, 27−61 is the same as (33)−61. Applying the negative exponent rule, which states that a−b1=ab, we get (33)6.
Simplify Choice (B): Applying the power of a power rule again, (33)6 becomes 3(3∗6) or 318. So, choice (A) is equivalent to 318.
Simplify Choice (C): For choice (B) 2712, we again recognize that 27 is 33. So, 2712 is the same as (33)12. Applying the power of a power rule, (33)12 becomes 3(3∗12) or 336. This is not equivalent to 318.
Simplify Choice (D): For choice (C) 1/276, we have 1 divided by 27 raised to the 6th power.As before, 27 is 33, so 1/276 is the same as 1/(33)6.This simplifies to 1/318, which is the reciprocal of 318, not equivalent to 318.
Simplify Choice (D): For choice (C) 2761, we have 1 divided by 27 raised to the 6th power.As before, 27 is 33, so 2761 is the same as (33)61.This simplifies to 3181, which is the reciprocal of 318, not equivalent to 318.For choice (D) 11, we have 27 raised to the 13th power.Since 27 is 33, 11 is the same as 17.Applying the power of a power rule, 17 becomes 19 or 270.This is not equivalent to 318.
