75+25+13+91+87+52+48+9

=(52+25)+(13+87)+(91+9)+(52+48)

=1000+100+100+100=100x4

=400

     A=54^5-54^4=54^4 . (54-1)

=>A=54^4 . 53

Why A, for 53

   Good luck

X+2/5=1/2

X=1/2-2/5

X=1/10

Good luck

x-2 /5=2/7

x=2/7+2/5

x=19/5

Good luck

0,256x8=2,048

X:1/7=14

X=14x1/7

X=2

    Ansew:

2^30=(2^3)^10=8^10

3^20=(3^2)^10=9^10

For 8^10<9^10=>2^30<3^20

                             Answer:

  15+10+30+70+10+90+85

=(15+85)+(10+90)+(30+70)+10

=100+100+100+10

=100x3+10

=310

a,2^3=2^x         b,25=5^x                   c,32=2^x

x=3                      25 =5^2                      32=2^5

You are not need to register because the online math is help for the solution

Thank you

  Answer:

8^7-2^18=(2^3)^7-2^18=2^21-2^18=2^17x(2^4-2)=2^17x14;14
