Answer 1

ex 4 
a) 7*(16-15)-(25-9)/4= 7*1-16/4= 7-4=3
b) (15^35+3^8) / (3^8+15^35)=1 
c) [2^80+(2^5*3^5)*3^7+2^9)/[2^80+(2^12*3^12)/2^7+2^9]=(2^80+2^5*3^12+2^9)/(2^80+2^5*3^12+2^9)=1
d) {[(9*49-16*25)/41+(4*49+4)/25]^3-649}/4={[(441-400)/41+(200/25)]^3-649}/4=[(1+8)^3-649]/4=(729-649)/4=80/4=20
e) [(32*25-8*25)/(8*75)+12+5^3/5^2]/9=[(800-200)/600+12+5]/9=(1+17)/9=18/9=2
f){[(827-27)/32+3*8*25]/625+1330}/1331=[(800/32+600)/625+1330]/1331=(625/625+1330)/1331=1331/1331=1
g){[(15*19+4)/17+128-343/(361-18)]/48+153}/39=[17+128-343/343]/48+153]/39=(144/48+153)/39=(3+153)/39=158/39=4
h) 2^101/[(5-3)^98+2^105/2^7+2^99]=2^101/(2^98+2^102+2^99)=2^101/[2^98(1+2^4+2)]=2^101/2^98*(1+16+2)=2^3*19=8*19=152
