48

Explanation:

PEMDAS stands for Parentheses, Exponent, Multiply, Divide, Add, and Subtract. First. start with the parentheses. Inside the parentheses, we have:

4-3^2

Solve the exponent first. 3^2=9. So we have:

4-9

This becomes -5. Now that we solved inside the parentheses, we're left with:

0.6(-5)-:1/4^2

Exponents take precedence over multiplication and division. Solve for 4^2. We get 16 in the denominator. So we have:

0.6(-5)-:1/16

Multiplication and division have equal precedence. So we solve from left to right:

0.6(-5)=-3

So now we have:

3-:1/16

If you're dealing with fractions, you can flip the fraction and change the sign to a multiplication symbol. So we can rewrite it as:

3xx16

Solve:

3xx16=48
