Find the difference (4ab-9a-8)-(7ab-1)

1 answer:

7 0

(4ab - 9a - 8) - (7ab - 1)
distribute (multiply) the negative through the parenthesis
(4ab - 9a - 8) - 7ab + 1
No need for other parenthesis because nothing in front or to combine inside. 
4ab - 9a - 8 - 7ab + 1 
Combine like terms
- 3ab - 9a - 7

4)^-5 write in a simplified fraction

erastova [34]

$\bf 4^{-5}?\qquad \textit{well, bear in mind that}\\
----------------------------\\
a^{-{ n}} \implies \cfrac{1}{a^{ n}}\qquad \qquad

\cfrac{1}{a^{ n}}\implies a^{-{ n}}
\\ \quad \\
% negative exponential denominator
a^{{ n}} \implies \cfrac{1}{a^{- n}}
\qquad \qquad 

\cfrac{1}{a^{- n}}\implies \cfrac{1}{\frac{1}{a^{ n}}}\implies a^{{ n}}\\
----------------------------\\
thus\implies 4^{-5}\implies \cfrac{1}{4^{+5}}\implies \cfrac{1}{4^5}\implies \cfrac{1}{1024}$

What is 26 percent of 2.21

Rashid [163]

You have to do mutiplication. how do you know that you have to do mutiplcation because the (of) it means times. so 26 * 2.21 = 0.5746
2.21/x=100/26
(2.21/x)*x=(100/26)*x 
2.21=3.8461538461538*x
(3.8461538461538) to get x
2.21/3.8461538461538=x 
0.5746=x 
x=0.5746
