The main property is as follow
(A^p)^q=A^pxq
so only Sam's work is correct because
(8^4)^5 x(7^3)^9=(8^4x5)x(7^3x9)=8^20x 7^27
I don't really speak Spanish but I'll guess that says
How do I solve y = 1 - 2.5
Unless I'm missing something, there's not even any algebra here.
The way we subtract a bigger number from a smaller number is first we subtract the smaller number from the bigger number the regular way, then we prepend a minus sign.
y = 1 - 2.5 = -(2.5 - 1) = -1.5
1) Work out what 1/5 of 12 is
To do this, we divide 12 by 5
12/5 = 2.4
2) Multiply 2.4 by 15
2.4 x 15 = 36
<em>If you don't like decimals, you can also do it this way...
</em>
This can be rewritten as 15 x 1/5 x 12
Multiplications alone can be performed in any order
1) Work out what 1/5 of 15 is
1/5 of 15
15/5 = 3
2) 3 multiplied by 12
3 x 12 = 36
Answer:
2/25
Step-by-step explanation:
It will be 20/400 + 12/400
=2/25
