Answer 1

a) 10^60:(2x5)^58=10^60:10^58=10^60-58=10^2=100

b) (7^14x5)^2:7^26=(7²⁸x5²):7²⁶ ==7²x5² ==(7x5)² =35² =1225

c) (7⁶)⁸:49²⁴=7⁴⁸:(7²)²⁴ =7⁴⁸:7⁴⁸ =7⁰  =0

d)(3⁴)⁹:(9⁶)³=3³⁶:[(3²)⁶]³  =3³⁶:3³⁶  =3⁰ =0

e) 11^2011 × 4^1005) : [(22^2)^5]^201 =(11^2011 × 2^2010) : ( 22^10)^201 =(11^2011 × 2^2010) : ( 22^2010) =(11^2011 × 2^2010) : (2 ^2010 × 11^2010) =11 ^(2011 - 2010) × 2^2010 : 2^2010) =11^1 × 1 =11

f)2²³:2²¹:2+3³²:3³¹x3=2²³⁻²¹⁻¹+3³²⁻³¹⁺¹  =2¹+3² =2+9  =11
