Question

$$(-2)^{k+1}+(4^{2})^{k}=(-2)^{7}$$

Verify

$\text{false}$

Solution Steps

Calculate $-2$ to the power of $2$ and get $4$.

$$4+4^{2}=\left(-2\right)^{-2}$$

Calculate $4$ to the power of $2$ and get $16$.

$$4+16=\left(-2\right)^{-2}$$

Add $4$ and $16$ to get $20$.

$$20=\left(-2\right)^{-2}$$

Calculate $-2$ to the power of $-2$ and get $\frac{1}{4}$.

$$20=\frac{1}{4}$$

Convert $20$ to fraction $\frac{80}{4}$.

$$\frac{80}{4}=\frac{1}{4}$$

Compare $\frac{80}{4}$ and $\frac{1}{4}$.

$$\text{false}$$
