Find 2 ways to get four fives to equal 30?
5(5 + 5/5) or (5/5+5)*5 and 5*5 + sqrt[5*5] and 5*5 + (5 squared)/5
What is the simplified expression for 1 plus radical 5 over 5 plus radical 5?
The trick here is to multiply by the value 1, but express it as (5 - √5)/(5 - √5). This forms a difference of squares on the bottom, eliminating the radical:(1 + √5) / (5 + √5)= (1 + √5)(5 - √5) / (5 + √5)(5 - √5)= (5 - √5 + 5√5 - 5) / (25 - 5√5 + 5√5 - 5)= 4√5 / 20= √5 / 5
What is the answer to 5x 8?
Think 5 groups of 8 each. 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 5 x 8 = 40
What is five to the negative 1st power?
1/5 When you have any number to the negative power, it becomes a fraction: 5^-1 = 1/5 5^-2 = 2/5 5^-3 = 3/5 5^-4 = 4/5 5^-5 = 5/5 5^-6 = 6/5 5^-7 = 7/5 5^-8 = 8/5
5 as a fraction of 25?
5/25 = divide top and bottom by 5: (5/5)/(25/5)= 1/5 5 is 1/5 (one fifth) of 25
Can you find a way to get four fives to equal 17?
(5/5)*(5/5)=1 (5/5)+(5/5)=2 (5+5+5)/5=3 sqrt(5+5)-(5/5)=4 sqrt(5+5)*(5/5)=5 sqrt(5+5)+(5/5)=6 5+((5/5)/5)=7 5+.5+(5*.5)=8 (5+5)-(5/5)=9 sqrt(5+5)+sqrt(5+5)=10 5+5+(5/5)=11 (5*5*.5)-.5=12 (5*5*.5)+.5=13 ((5!/5)*.5)+5=17 (5!/5)*sqrt(5*5)=19 5*5-sqrt(5*5)=20 (55/5)/.5=22 (5!/5)-(5/5)=23 (5!/5)-(5-5)=24 (5!/5)+(5/5)=25 (5*5)+(5/5)=26 (55*.5)-.5=27 (55*.5)+.5=28 (5!/5)+sqrt(5*5)=29 5*5+sqrt(5*5)=30
How do you create equations that equals the numbers 1-10 using five 5's for each?
1 = (5 - 5)*5 + 5/52 = [(5+5)/5]*(5/5)3 = (5+5)/5 + 5/54 = (5+5+5+5)/55 = (5/5)*(5/5)*56 = (5*5)/5 + 5/57 = (5*5 + 5 + 5)/58 = (5+5+5)/5 + 59 = (5*5 - 5)/5 + 510 = (5*5 + 5*5)/5
