Question

pls answer this questions

Answer 1

.10. Draw a line segment PQ=8.47 unit
Produced Q to C such that QC=1 unit
Find the mid-point of line segment PC and mark it as D
Now taking D as centre and radius DP , draw a semicircle.
Now Draw a perpendicular from point Q which intersects the semicircle at E.
Produce PC to 3 or 4 unit.
Now taking Q as centre and QE as radius
Draw an arc which intersects the line segment at F.
Then QF= root 8.47

11. 3^x-1=9
3^x-1=3^2
x-1=2
x=3
and 4^y+2=64
4^y+2=4^3
y+2=3
y=1
So x/y=3/1=3
hope it helps
plz mark brainliest

Answer 2

3^ x-1 =9
3^x-1= 3^2
x-1=2
x= 3
4^ y+2= 64
4^y+2= 4^3
y+2 = 3
Y=1
Value of x/y = 3/1=3
