Question

REPEDEEEE!!!!!!!!
Efectuati:
a) (10²-6²):2³
b) 1+2×[3²×(13×2-5²)+1]
c)9²supra5÷(3×3¹¹)⁴+(6+2×105)6²
d) (7¹ supra 15²⁴supra 0):(5 supra 72:5 supra 70:5)
e) [(3³)supra 15:3 supra 6 supra 2-3³ supra ²]×513²³.

Answer 1

a)(100-36):8=64:8=8
b)1+2x[9X(13X2-25)+1=1+2X(9X1)+1=1+2X9+1=19

Answer 2

a)(10-6)^2÷2^3=4^2÷2^3=2^4-2^3=2
b)1+2[3^2×(13×2-25)+1]=
1+2×(9×1+1)=1+2×10=21
