-(w-x)-(-x-w)
= x-w+x+w
= 2x
(5 x 10-1)2 Actually that's not a good way to express this equation.
The best way:
2(5 x 10 - 1)
= 2 x 5 x 10 - 2
= 100 - 2
= 98
\(a^{\frac{10}{3}}b^{\frac{7}{3}}= \sqrt[3]{a^{10}b^7}\)
A few tricks for you......
11x54 = 594
5 x 14 = 5 x 2 x 7 = 10 x 7 = 70
25 x 44 = 25 x 4 x 11 = 100 x 11 = 1100
9 x 54 = 486
T=n^2
aka
T=n2
a^b means a to the power of b
base times half of height.
I agree.
Good morning our guest.
The first thing you do, if you see brackets, you do the math in the brackets first.
Example(Examples always help understanding):
7+(6+7)x2
= 7 + 13 x 2
= 7 + 26
= 33
\(\frac{68-62}{62}=\frac{6}{62}\)
Which is approximately 10%
