Question

simply 7+3√5 / 7-3√5 by rationalize the denominator​

Answer 1

Answer:

(47+21root5)/2

Step by step explanation:

(7+3root5)/(7–3root5)

5)Let us rationalize the denominator, we get

5)Let us rationalize the denominator, we get(7+3root5)/(7–3root5)=[(7+3root5)(7+3root5)]/[(7–3root5)(7+3root5)]

5)]=[(7+3root5)2]/[72–(3root5)2]

5)2]=[72+(3root5)2+2.7.3root5]/[49–9.5]

5]/[49–9.5]=[49+9.5+42root5]/[49–45]

5]/[49–45]=[49+45+42root5]/[4]

5]/[4]=[94+42root5]/4

5]/4=2[47+21root5]/4

5]/4=[47+21root5]/2
