simplify (9sqrt(21))^2

Solution

simplify

(921)^{2}

Solution

1701

Solution steps

(921)^{2}

Apply exponent rule:

(a \cdot b)^{n} = a^{n} b^{n}

(921)^{2} = 9^{2} (21)^{2}

= 9^{2} (21)^{2}

9^{2} = 81

= 81 (21)^{2}

(21)^{2} = 21

= 81 \cdot 21

Multiply the numbers:

81 \cdot 21 = 1701

= 1701

∣ 3 (x - 1) ∣ = 8

2-(2x-1)/3+(1-3x)/7 =7-2x

2 - \frac{2 x - 1}{3} + \frac{1 - 3 x}{7} = 7 - 2 x

simplify (a-3b)/(a^2-3ab)simplify

\frac{a - 3 b}{a ^{2} - 3 ab}

simplify (1.01*10^{-14})/(2.2*10^{-8)}simplify

\frac{1.01 \cdot 1 0 ^{- 14}}{2.2 \cdot 1 0 ^{- 8}}

2 = m^{2} + 4
