What is the answer to this question please explain (picture included)

Yakvenalex [24]

Easy peasy
just use PEMDAS and some exonential laws

$(x^{m})(x^{n})=x^{m+n}$
$(x^{m})^{n}=x^{mn}$
$(ab)^{m}=(a^{m})(b^{m})$

also another is $x^{\frac{m}{n}}=\sqrt[n]{x^{m}}$

so

$[3(2a)^{\frac{3}{2}}]^{2}$ =
$(3^{2})((2a)^{\frac{3}{2}}^{2})$ =
$(9)((2a)^{\frac{3}{2}}^{2})$ =
$(9)((2a)^{\frac{6}{2})$ =
$(9)((2a)^{3})$ =
$(9)(8a^{3})$ =
$72a^{3}$

How do I do 3 x 10^5

Ilya [14]

Answer: 3(10^5)

=3*10^5

=3*(10*10*10*10*10)

=300000

This is how you should do It, just when it is squared you should times the number like up here you times 10 times 10 5 times so if you see it you don't times it by 5 you do 10 times 10 times 10 times 10 times 10 like this

You should get it now

Have a good day

Yours,

At a farmers market you buy 4 pounds of toamtoes(3$ each) and 2 pounds of sweet potatoes (2$ each). You spend 80% of he money in

Artyom0805 [142]

4*3=12
2*2=4
12+4=16
16/4=4
4*5=20
Therefore, $20 was the original amount of money in your wallet.

Find the limit if it exists lim x→0 sqrtx+7-sqrt7 over x

Triss [41]

Answer:

$\frac{1}{ 2\sqrt{7} }$

Step-by-step explanation:

$\lim_{x\to 0} \frac{ \sqrt{x + 7} - \sqrt{7} }{x} \\ \\ = \lim_{x\to 0} \frac{( \sqrt{x + 7} - \sqrt{7}) }{x} \times \frac{( \sqrt{x + 7} + \sqrt{7}) }{( \sqrt{x + 7} + \sqrt{7}) } \\ \\ = \lim_{x\to 0} \frac{( \sqrt{x + 7} )^{2} - (\sqrt{7})^{2} }{x( \sqrt{x + 7} + \sqrt{7})} \\ \\ = \lim_{x\to 0} \frac{( {x + 7} - {7}) }{x( \sqrt{x + 7} + \sqrt{7})} \\ \\ = \lim_{x\to 0} \frac{ {\cancel x}}{\cancel x( \sqrt{x + 7} + \sqrt{7})} \\ \\ = \lim_{x\to 0} \frac{ {1}}{\sqrt{x + 7} + \sqrt{7}} \\ \\ = \frac{1}{ \sqrt{0 + 7} + \sqrt{7} } \\ \\ = \frac{1}{ \sqrt{7} + \sqrt{7} } \\ \\ = \frac{1}{ 2\sqrt{7} }$
