Simplify.<br> Rewrite the expression in the form b^n<br><br> (b^3)^2

Alexxandr [17]

Step-by-step explanation:

$a^n={\underbrace{a\cdot a\cdot a\cdot...\cdot a}_{n}$

<h2>METHOD 1.</h2>

$\left(b^3\right)^2=\underbrace{b^3\cdot b^3}_{2}=\underbrace{b\cdot b\cdot b}_{3}\cdot\underbrace{b\cdot b\cdot b}_{3}=\underbrace{b\cdot b\cdot b\cdot b\cdot b\cdot b}_{6}=b^6$

<h2>METHOD 2.</h2>

$\left(b^3\right)^2=\underbrace{b^3\cdot b^3}_{2}=b^{3+3}=b^6\qquad\text{used}\ a^n\cdot a^m=a^{n+m}$

<h2>METHOD 3.</h2>

$\left(b^3\right)^2=\left(\underbrace{b\cdot b\cdot b}_{3}\right)^2=b^2\cdot b^2\cdot b^2=b^{2+2+2}=b^6\\\text{used}\ (ab)^n=a^nb^n,\ a^n\cdot a^m=a^{n+m}$

<h2>METHOD 4.</h2>

$\left(b^3\right)^2=b^{3\cdot2}=b^6\qquad\text{used}\ \left(a^n\right)^m=a^{nm}$

C+ax=dx<br><br><br>this one has all variables and no numbers

sergeinik [125]

That's OK, but you have not said which variable you want to solve it for.

<u>To solve for 'x':</u>
   <span>c + ax = dx

Subtract c from each side: ax = dx - c

Subtract dx from each side: ax - dx = -c

Factor the left side: x (a - d) = -c

Divide each side by (a - d) :    x = -c / (a - d) or <u>x = c / (d - a)</u> .

</span><span><u>To solve for 'c': </u>
</span><span>   c + ax = dx

Subtract ax from each side and factor: <u>c = x (d - a) </u>

</span><u>To solve for 'd': </u>
      <span>c + ax = dx

Divide each side by 'x':   d = c/x + a .

<u>To solve for 'a':</u>
</span><span><span>   c + ax = dx</span>

Subtract 'c' from each side: ax = dx - c

Divide each side by 'x': <u>a = d - c/x </u>.
