Simplify the following:

i) [tex][tex]$(-3) \times(-2)^3$[/tex][/tex]

Sagot :

Sure, let's simplify the expression [tex]\((-3) \times (-2)^3\)[/tex] step-by-step.

1. Deal with the exponent first:
Calculate [tex]\((-2)^3\)[/tex]. When raising [tex]\(-2\)[/tex] to the power of 3, we multiply [tex]\(-2\)[/tex] by itself three times:

[tex]\[ (-2)^3 = (-2) \times (-2) \times (-2) \][/tex]
Multiply the first two [tex]\((-2)\)[/tex]'s:

[tex]\[ (-2) \times (-2) = 4 \][/tex]
Now, multiply the result by [tex]\(-2\)[/tex] again:

[tex]\[ 4 \times (-2) = -8 \][/tex]
So, [tex]\((-2)^3 = -8\)[/tex].

2. Multiply the result by the coefficient:
Now we need to multiply [tex]\(-3\)[/tex] by [tex]\(-8\)[/tex]:

[tex]\[ (-3) \times (-8) \][/tex]
The product of two negative numbers is a positive number, so:

[tex]\[ (-3) \times (-8) = 24 \][/tex]

So, the simplified result of [tex]\( (-3) \times (-2)^3 \)[/tex] is [tex]\( 24 \)[/tex].
