1. The expression is equivalent to x⁻⁶, which corresponds to option (4).

2. The correct way to rewrite the function y = 16(2ˣ) is
y = 2^(4+x). Option 3

How do we find the equivalent expressions?

1. The power rule for exponents, which states that
(a^m)^n = a^{(m*n)

Using this rule, The expression
((1)/(x^3))^2 becomes
(x^(-3))^2 =
x^(-3*2) = x⁻⁶

Therefore, the expression is equivalent to x⁻⁶

2. The exponential function y = 16(2ˣ) can be rewritten by incorporating the constant 16 as a power of 2 since 16 is 2⁴.

y = ( 2⁴)(2ˣ)

Using the property of exponents that
a^m * a^n =
a^(m+n)

we can combine the terms;
y = 2^(4+x)
