Answer 1

Answer:

5$\frac{1}{2}$

Step-by-step explanation:

The cube root of a number is a number that, when multiplied by itself twice, equals the number in the cube root.

So, the cube root of 343 is 7 because 7 * 7 * 7 = 343.

Now the expression looks like: 7 + $\frac{3}{4}$$\sqrt[3]{-8}$

The cube root of -8 is -2 because -2 * -2 * -2 = 8

Now the expression is: 7 + $\frac{3}{4}$(-2)

3/4 * -2 = -6/4, or -1 and 1/2

7 - 1 1/2 = 5 and 1/2

Answer 2

Answer:

the answer is 5.1/2 ok because cube root of 343 is 7 and cube root of -8 is -2 ok the answer is 5.1\2
