2³+2³+2³+2³=2^x find x |
Answer» Given:-2³ + 2³ + 2³ + 2³ = 2^x To Find:-VALUE of x. Solution:-
2³ + 2³ + 2³ + 2³ = 2^x Taking 2³ as common •°• 2³( 1 + 1 + 1 + 1) = 2^x 2³ × 4 = 2^x WRITE 4 as exponential form 2³ × 2² = 2^x 2³ + ² = 2^x 2⁵ = 2^x since 2 = 2 on both the side •°• x = 5
2³ + 2³ + 2³ + 2³ = 2^x 8 + 8 + 8 + 8 = 2^x 16 + 16 = 2^x 32 = 2^x write 32 in exponential form 2⁵ = 2^x °•° 2 = 2 •°• x = 5
