Answer:

Step-by-step explanation:

75^{30}\\\\75=3\cdot5\cdot5=3\cdot5^2\\\\75^{30}=(3\cdot5^2)^{30}=3^{30}\cdot(5^2)^{30}=3^{30}\cdot5^{60}

45^{45}\cdot15^{15}\\\\45=3\cdot3\cdot5=3^2\cdot5\\15=3\cdot5\\\\45^{45}=(3^2\cdot5)^{45}=(3^2)^{45}\cdot5^{45}=3^{90}\cdot5^{45}\\15^{15}=(3\cdot5)^{15}=3^{15}\cdot5^{15}\\\\45^{45}\cdot15^{15}=3^{90}\cdot5^{45}\cdot3^{15}\cdot5^{15}=3^{90+15}\cdot5^{45+15}=3^{105}\cdot5^{60}\\\\=3^{75+30}\cdot5^{60}=3^{75}\cdot\underbrace{3^{30}\cdot5^{60}}_{75^{30}}=3^{75}\cdot75^{30}

\text{therefore it is divisible by}\ 75^{30}

Used:\\\\(ab)^n=a^nb^m\\\\(a^n)^m=a^{nm}\\\\a^n\cdot a^m=a^{n+m}

A line intersects the points (-5, 1) and (-2,7). What is the slope of the line in simplest form? m=[?}
IrinaK [193]

Step-by-step explanation:

To find slope : y2- y1 / x2 - x1

we have ( -5 , 1 ) which is ( x1 , y1 )

and ( -2 , 7 ) is ( x2 , y2 )

so; 7 - 1 / -2 - (-5)

6/3

= <u>2</u>

How do you invert and multiply to divide 2/3÷4
Ira Lisetskai [31]
2/3  ÷  4

2/3 ÷ 4/1

We invert the 4/1 to 1/4 and multiply out.

2/3  ×  1/4

= 1/3 × 1/2                              2 into 4 is 2.

= 1/(3 × 2)

= 1/6

Hope this helps.

Expand and simplify 4(x 5)-2(x-3)
NISA [10]
If you would like to simplify <span>4(x + 5) - 2(x - 3), you can do this using the following steps:

</span>4(x + 5) - 2(x - <span>3) = 4x + 4 * 5 - 2x + 2 * 3 = 2x + 20 + 6 = 2x + 26
</span>
If you would like to simplify <span>4(x - 5) - 2(x - 3), you can do this using the following steps:

</span>4(x - 5) - 2(x - <span>3) = 4x - 4 * 5 - 2x + 2 * 3 = 2x - 20 + 6 = 2x - 14</span>
