Answer:
x−4=3⇒x−4+4=3+4⇒x=7
Hence, x = 7 is the solution of the equation.
(2) 9m = 81, m = 3, 9, −3
9m=81Dividing both sides by 9⇒9m9=819⇒m=9
Hence, m = 9 is the solution of the equation.
(3) 2a + 4 = 0, a = 2, −2, 1
2a+4=0⇒2a+4−4=−4⇒2a=−4Dividing both sides by 2⇒2a2=−42⇒a=−2
Answer:
9 is the answer
Step-by-step explanation:
you you should rationalize each time by multiply them with their conjugated.
for eg.
(1/√1+√2)*(√2-√1)(√2-√1)
which gives out √2-√1
second term→√3-√2
third term→√4-√3
.......goes on........
last term→√99-√100
observe that except (√1)&(√100), all terms cancel out.
the answer is -√1+√100
=-1+10
=9
