X^3×3=4! X^3=2×4×3/3 X^3=8 X^3=2^3 X=2

Главное чтоб из ледяной води витащили

(C)√3

1 and 2

(C) 2

x=9^2=81

16 + root(x) = 25.... x=81

Is = 4! , not 4 .😂 So 3(x^3) = 24 , x^3 = 24/3 = 8 x = 8^(1/3) = 2

3^(x√2) = 3^(√8)/3^(√2) 3^(x√2) = 3^(2√2)/3^(√2) 3^(x√2) = 3^(2√2-√2) 3^(x√2) = 3^(√2) x = 1

(125+100)/125x100= 225/125x100= 9/5x100)= 9/500

(2^6x2^4)^1/5= (2^6+4)^1/5= 2^10x1/5= 2^2=4

9^x(2^x-1)=9^x•3 2^x-1=3 2^x=2^2 x=2

X=1/3

A more accurate numerical estimate for x is 3.465

Answer A

1% of 902 is 9.02, 8 times which is 72.16.

3 ^x . 3^x . 3^x = 81, 3 ^x + x + x = 3⁴, 3^3x = 3⁴, 3x = 4, x = 4/3, b) 4/3 is the right answer.

Your sums are always easy.

Wow nice 👍👍👍👍👍

(√7)^(√(24-√x)) = 49 (√7)^(√(24-√x)) = (√7)^4 √(24-√x) = 4 24-√x = 16 -√x = -8 √x = 8 x = 64

1/4

In my head: sqrt(7)^4 =49 sqrt(7)^sqrt(16) = 49 16 = 24 - sqrt(x) 16 = 24 - 8 sqrt(x) = 8 x = 64 (C)

Answer D 1/4

X=1

Trop d'étapes

C'est possible de la résoudre dans une ligne

(2^10+2^2)*(2^10-2^2)=(1024+4)*(1024-4)= 1028*1020=(1000+28)*(1000+20)=1000000+48000+560= 1048560

4+5=9×9=81Ans

or: √2×(1+√X/√2)/√2=4 1+√X/√2=4 √X/√2=4-1=3 √X=3×√2 X=3^2×(√2)^2 X=9×2 X=18

Really good explanation but I think it's too long😊

3^3^3 ＝3^27 27^3² ＝27^9 どっちもlog₃をとると log₃3^27＝27 log₃27^9＝27 だから3は合ってる

x^x^3＝27^x^2 logx^x^3＝27^x² x³logx＝x²log27 難しい

指数法則 √9^x＝9 両辺を2乗 9^x＝81 両辺に底が9の対数をとる log_9 9^x＝log_9 9² xlog_9 9＝2log_9 9 両辺をlog_9 9で割る x＝2
