Which equations are correct?

Leno4ka [110]

9514 1404 393

Answer:

C, D

Step-by-step explanation:

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

__

The correct equations are the last two.

For the first two, the appropriate products are ...

$4c^4(3c^2)=4\cdot3c^{4+2}=12c^6\\\\3b^3(a^2b^4)=3a^2b^{3+4}=3a^2b^7$

Need help on this plzz

Aleksandr [31]

I do believe that it's one of the bisected ones. bisect is the line that splits the middle and D is definitely wrong. So that should narrow it down. So I would go with A or B. Sorry if I didn't help much but it's better than having no clue.

Change this radical to an algebraic expression with fractional exponents.

vekshin1

Rational exponents

$a^\frac{m}{n}$

work like this: the numerator is the actual exponent of the base, while the denominator is the index of the root.

In other words, we have

$a^\frac{m}{n}=\sqrt[n]{a^m}$

So, in you case, we have

$\sqrt[5]{x^3}=x^\frac{3}{5}$

Assuming that the question contanis a typo. If you actually mean $5\sqrt{x^3}$ ,

then you can write it as $5x^\frac{1}{3}$

A = 8: b = ; C = 10.

lara [203]

Answer:

b=6

$a^{2} + b^{2} = c^{2} \\ {8}^{2} + {b}^{2} = {10}^{2} \\ 64 + {b}^{2} = 100 \\ 100 - 64 = {b}^{2} \\ 36 = {b}^{2} \\ \sqrt{36} = \sqrt{ {b}^{2} } \\ 6 = b$
