Question

Add parentheses to make true.


2(with exponent of 3) +7.8 + 4 = 30.

Answer 1

8 (hopefully)

Explanation:

Exponents and Fractions always get dealt with before Math Symbols and Parentheses.

But other than that, you ALWAYS do times or divide from left to right, than plus or minus left to right (unless there's a parentheses, go for the number in the parentheses).

2 by the power of 3 (or 2^3) splits into three twos.

2 * 2 = 4 * 2 = 8 (2^3 = 8)

7 * 8 = 56

56 divided by 4 = 14

8 + 14 = 22

Long story sort

2^3 + 7 * 8 */. 4

8 + 7 * 8 */. 4

8 + 56 */. 4

8 + 14

22

Now than I do not remember what you're supposed to with the "= [Number]" but I do believe you're supposed to sum the left and the right. So I do believe it's 8, now than remember this is not an exact answer, due to not knowing what it's properly to be.

Answer 2

(2³ +7)·8÷4 = 30

Explanation:

You want to add parentheses to make a true statement from ...

2³ +7·8÷4 = 30

Order of operations

We recognize that 2³ +7 = 15 and 8÷4 = 2, and the product of these is 30. So, we need to insert parentheses to make (2³ +7) be evaluated before multiplying by 8 and dividing by 4:

(2³ +7) · 8 ÷ 4 = 30
