To evaluate the expression, substitute the values of a and b into the given expression:
1/(2a^6 - 4b^2)
= 1/(2(-2)^6 - 4(4)^2)
Simplifying further:
= 1/(2(64) - 4(16))
= 1/(128 - 64)
= 1/64
Therefore, the value of the expression when a = -2 and b = 4 is 1/64, which is not listed as an option.
evaluate 1/2a6-4b^2 for a=-2 and b=4
a ) 2
