Reduction of 9 / 4 under radical sign - radical 2 Come on, let's go! Hurry!

Reduction of 9 / 4 under radical sign - radical 2 Come on, let's go! Hurry!

9 / 4 = 3 / 2
9 / 4 under root sign - root 2
=3 / 2 - radical 2

What is the result of 4 + 9 / 4 minus 5 / 2 under the root sign?

4 + 9 / 4 minus 5 / 2
=√4+9/4-10/4
=√39/4
=(√39)/2

How to simplify Radix 48 Mainly tell me the method, step by step, give me a series of equations can not understand

√48
=√（3x16）
=√(3x4²)
=4√3

How to simplify the radical 1 / 48

1 / 48 = 144 / 3 = 3 / 12

Why is root 12 reduced to 2 and root 3? Who can tell how to simplify

12 = 3 times 4 root sign four equals two, so four can be opened and three left in the root sign, so it is equal to the root three of two times

Simplification (2 root sign 12 + 3 root sign 48) * 3 root sign 2 (2 times root number 12 + 3 times root number 48) * 3 times root number 2

(2 times root number 12 + 3 times root number 48) * 3 times root number 2
=(4 times root number 3 + 12 times root number 3) * 3 times root number 2
=16 times root number 3 * 3 times root number 2
=48 times root number 6

The root 48 is reduced to root 6 times root 8, which is equal to right or less

Radix 48 is reduced to Radix 6 times Radix 8 equal to 4 times Radix 3

The root number is 6 / 2, the root number is 12 + the root number is 48-2 times, and the root sign 1 / 2 is equal to the? Process

Root number 6 times root number 12 + root number 48-2 times root number 1 / 2
=√2+4√3-√2
=4√3

Reduction root 48-2 times root 3

Root number 48-2 times root number 3
=√16×√3-2×√3
=4×√3-2×√3
=Double root 3

If Tana / (tana-1) = - 1, then Sina 2 + sinacosa + 2=

From the question, Tan α = - 1 / 2, we can get sin? α = 0.2 and sinacosa = - 0.4
The original formula = 0.2-0.4 + 2 = 1.8
