who knows these?

I am soo confused on these!!!!!!!!! im going to blow!

x=2, y+3, a=4over 5 as a fraction, b=3 over 5 as a fraction.

1) 23-(a+b)

2) (10x)2 (2 is an exponent) +100a

3) a2(2 is an exponent)+2b

4) x+z divided by xz

5) (z divided by x)2(the exponent) +ax

please just dont give me the answers, but actually explain in steps how you got the answer. thanks!

MATH MAN TO THE RESCUE!!!!

1) 23 – (4/5 + 3/5) = 23 – 7/5 = 115/5 – 7/5 = 108/5

2)(10x)^2 + 100a = (20)^2 + 80 = 480

3) a^2 + 2b = 16/25 + 6/5 = 16/25 + 30/35 = 46/25

4)(2+z)/2z = I need the value for z…

5) (z/2)^2 + 8/5 = I need the value for z…

I don’t have the value for z, but I wrote the equation out

HOPE IT HELPS!!

I think y=3 , not y+3

1) 23- (a+b)

23-(4/5+3/5)=

=23-(7/5)=

=23-1and 2/5=

=23-1,4=

=21,6

2) 100×2(2 is an exponent) + 100a=

=100×2 + 100*4/5=

=100×2 + 80=

= 100*4 +80=

=480

3) a2 +2b=

=a2+ 6/5=

=16/25 + 30/25=

=46/25= 1 and 21/25

z=?
