Prove that the value of the expression: (5^18–25^8)(16^4–2^13–4^5) is divisible by 30 and 44.
makvit [3.9K]

The value of the expression is not divisible by 30 and 44.

<u>Explanation:</u>

(5^1^8 - 25^8) (16^4-2^1^3-4^5)\\=(5^1^8 - 5^2^\times^8) (2^4^\times^4 - 2^1^3 - 2^2^\times^5)\\=(5^1^8 - 5^1^6)(2^1^6-2^1^3-2^1^0)\\=(5^2) ( 2^3-2^1^0)\\=(25) (8-1024)\\=(25) \times (-1016)\\= -25400

To check the number -25400 be divisible by 30 and 44, divide the number -25400 by 30 and 44

On dividing -25400 by 30 we get, -846.66

On dividing -25400 by 44 we get, -577.27

Therefore,

The value of the expression is not divisible by 30 and 44.

A pack of gum is in the shape of a rectangle prism with a length of 8 centimeters and width of 2 centimeters. The volume of the
victus00 [196]
Hello!

We know that the length of the pack is 8 cm, width is 2 cm, and the volume is 48 cm^3.

The formula for volume is:

V = l × w × h

We don't want to find the volume...we already have that!

But we can use the volume and the length and width to find the height.

Since we multiply the dimensions to find the volume, we'll have to do the opposite to find a dimension.

And what's the opposite of multiplication? Division!

H = V ÷ lw

Multiply the length by the width, then divide the volume by that.

H = 48 ÷ 8(2)

H = 48 ÷ 16

H = 3

We can double check by using this to find the volume.

V = 8 × 2 × 3

V = 48

This means we're right!

ANSWER:

The height of the pack of gum is 3 centimetres.
