Write the expression in repeated multiplication form. Then write the expression as a power. (-8)^3*(-8)^4 The expression in repe

Makovka662 [10]

Given:

The expression is

$(-8)^3\cdot (-8)^4$

To find:

The expression in repeated multiplication form and then write the expression as a power.

Solution:

We have,

$(-8)^3\cdot (-8)^4$

The repeated multiplication form of this expression is

$=[(-8)\cdot (-8)\cdot (-8)]\cdot [(-8)\cdot (-8)\cdot (-8)\cdot (-8)]$

$=(-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)$

Clearly, (-8) is multiplied seven times by itself. So,

$=(-8)^7$

Therefore, the repeated multiplication form of the given expression is $(-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)$ and the expression as single power is $(-8)^7$ .

one of the solution to this problem below is 8. what is the other solution? C^2-64=0 ( please show your work )

iris [78.8K]

${c}^{2} - 64 = 0$
This can also be represented as:
${c}^{2} - {8}^{2} = 0$
Using difference of two squares;
$(c - 8)(c + 8) = 0$
$c - 8 = 0 \: or \: c + 8 = 0 \\ \\ c = 8 \: or \: c = - 8$

Hope I helped? ☺️
