Iris found a value of 1/64 when she evaluated an expression.
Which could have been the expression Iris evaluated? Check all that apply.
A. 2^-6
B. 6^-4
C. 4^-3
D. (1/2)^-5
E. (1/4)^-3
A. 2^-6
= 1 / 2^6
= 1 / 2*2*2*2*2*2
= 1 / 64
B. 6^-4
= 1 / 6^4
= 1 / 6*6*6*6
= 1 / 1,296
C. 4^-3
= 1 / 4^3
= 1 / 4*4*4
= 1 / 64
D. (1/2)^-5
= 1 ÷ (1/2)^5
= 1 × 2/1^5
= 2^5
= 2*2*2*2*2
= 32
E. (1/4)^-3
= 1 ÷ (1/4)^3
= 1 × 4/1^3
= 4^3
= 4*4*4
= 64
Options A. 2^-6 and C. 4^-3 are equivalent to 1/64
