Question

Find all square roots of the number or write no square roots. Check the results by squaring each root. $$0.16$$

Short answer

The square roots of 0.16 are \( +0.4 \) and \( -0.4 \), which are verified as a square of each root gives 0.16.

Step-by-step solution

Find the Square Root

To determine the square root of a number, use the square root function. The square root of 0.16 is either \( +0.4 \) or \( -0.4 \) because a number can have two square roots: one positive and one negative. Thus, the two roots of 0.16 are \( +0.4 \) and \( -0.4 \).

Verify the Roots

Verify the roots by squaring each of them. The square of \( +0.4 \) is 0.16 and the square of \( -0.4 \) is also 0.16.
