Simplify the equation 32^3/5
scoundrel [369]
Ok so to simplify 32^3/5, you will need to know the steps, so I'll tell u the step by step solution. ;D

So Step 1: You have to <span>Raise 32 to the 3rd power:

</span><span><span>1.1 </span>    32 = 2</span>⁵
(32)³ = (2⁵)³ = 2¹⁵

<span>the equation has ended on step 1, so now is:

</span><span>  2</span>¹⁵
<span>------
  5
</span>
Now step 2:
Simplify it 

(you can't simplify this equation but these is the steps you gotta do on other equations so I'm just giving an example.)

  2¹⁵
------
  5

So basically your final result is:

  2¹⁵
------
  5

=====End=====

Hope you understand it :D

Can someone answer these questions ? thank you
Naya [18.7K]

Answer:

Step-by-step explanation:

12a)To rationalize the denominator, multiply the denominator and numerator by √5.

\frac{15}{\sqrt{5}}=\frac{15*\sqrt{5}}{\sqrt{5}*\sqrt{5}}\\\\=\frac{15\sqrt{5}}{5}\\\\=3\sqrt{5}

b) (a+b)² = a² + 2ab + b²

(1 +√3)² = 1² + 2*1*√3 + (√3)²

= 1 + 2√3 + 3

= 4 + 2√3

a = 4 ; b =2

13) (a + b)(a - b) = a² - b²

\frac{(6-\sqrt{5})(6+\sqrt{5})}{\sqrt{31}}=\frac{6^{2}-(\sqrt{5})^{2}}{\sqrt{31}}\\\\ =\frac{36-5}{\sqrt{31}}\\\\=\frac{31}{\sqrt{31}}\\\\=\frac{31*\sqrt{31}}{\sqrt{31}*\sqrt{31}}\\\\=\frac{31\sqrt{31}}{31}\\\\=\sqrt{31}

Help??( dont forget to explain)
Setler [38]

Answer:

You can decide where to put the first digit because you know 153 doesn't fit into 6 or 61. But you know it can fit into 613. You put it there.

Can you guy's help me quick!
nadya68 [22]

Answer:

480,700 sets (first choice)

Step-by-step explanation:

If all 25 questions are different,

When order of selection counts:

P(25,7)

= 25!/(25-7)!

= 15511210043330985984000000/6402373705728000

= 2422728000

When order of selection does not count count:

C(25,7)

=25!/(7!*(25-7)!)

=15511210043330985984000000/(6402373705728000*5040)

= 480,700

Hope this helps, have a nice day.
